Title: Siege a chassis de support de dos changeant de forme
Inventor: HEIDMANN KURT R
IPC: B60N2/00
Filed: 2006-02-28
Abstract: La présente invention a trait à un dossier comportant un châssis de dossier articulé et un support de dos. Le châssis de dossier présente un segment inférieur fixé en pivotement à un dispositif de commande de chaise, un segment supérieur pour le support du buste, et des liaisons formant une liaison à quatre barres avec les segments supérieur et inférieur, avec une articulation formée au niveau de la région lombaire. Le support de dos est extensible dans des directions limitées pour s'adapter à un changement de forme dans le châssis de dossier articulé pour assurer un support adéquat à un utilisateur qui y est assis. Lors de la réception d'une pression vers l'arrière sur l'articulation lombaire, le châssis de dossier lui-même change de forme. Les emplacements de pivot dans la liaison à quatre barres créent un mécanisme qui assure la commande simultanée de mouvement de rotation et de translation du segment supérieur lors de la flexion lombaire. Le châssis de dossier est proche du support de dos pour assurer une flexibilité de construction importante, tout en permettant une flexion lombaire substantielle. L'invention propose divers supports de dos qui s'adaptent à l'articulation du châssis de dossier.

     선회스크롤부재의 배면에, 제1의 프레임부재에 지지되고, 축방향으로 이동가능한 제2의 프레임을 배치하고, 제2의 프레임부재의 배면에 힘을 부여하여, 선회스크롤부재의 축방향의 미동을, 고정스크롤부재와 그 제2의 프레임부재에 의하여 규제한다. 이 결과, 양 스크롤 부재가 밀착 또는 미소간극을 가지고 밀접하여 원활한 운동이 확보되어, 고효율, 고신뢰성의 스크롤압축기를 얻을 수가 있다.

Abstract: A process for the production of a heat- and corrosion-resistant porous metal body which is made of a metal or whose surface layer is made of a metal, in which the porous metal body can be alloyed with chromium or a combination of chromium and aluminum uniformly throughout the entire thereof by adjusting the alloy composition in the following manner, i.e., (A) heat-treating the porous metal body in a mixed gas comprising a gas, generated by heating a powdered mixture comprising chromium or its compound and NH4Cl at 950 to 1100 DEG C, and a diluent reducing gas at 800 to 1100 DEG C, or (B) heat-treating the porous metal body in a mixed gas comprising a gas, generated by heating a powdered mixture comprising aluminum or its compound, chromium or its compound and NH4X, wherein X is I, F, Cl or Br, at a weight ratio of the chromium or its compound to the aluminum or its compound of 10 to 80 in terms of Cr and Al respectively at 950 to 1100 DEG C, and a diluent reducing gas at 800 to 1100 DEG C. <MATH>
